FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 358,293, dated February22, 1887.

Application filed February 15, 1886. Serial No. 191,972. (No model.)

To aZZ whom it may concern.-

Be it known that I, PAUL G. PARIS, a citizen of the United States,residing at Columbia, in the county of Richland and State of SouthCarolina, have invented certain new and useful Improvements inFire-Escapes; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to fire-escapes, and more particularly to thatclass known as lazytongs, and the object of the invent-ion is to provideimproved means for raising and lowering the tongs, and to provide thelazytongs with a platform and improved means for mounting the same.

With these ends in view the invention consists in the improvedconstruction and combinations of parts,hereinafter fully described, andpointed out in the claim. In the drawings, Figure l'is a perspectiveview of a fire-escape embodying my invention. Fig. 2 is a plan view withthe top or platform removed, and Fig. 3-is a detail longitudinalvertical section illustrating a modification. Fig. 4 is a verticaltransverse section through the platform shown in Fig.- 1.

Corresponding parts in the several figures are denoted by the sameletters of reference.

Referring to the drawings. A represents a rectangular frame, designed torest upon a truck, B, and from which frame extend uprights or standardsC, which arebraced by the beams b. Between the upper ends of theuprights or standards C is journaled a shaft, D, having bearing in boxesa, secured to the upper ends of the uprights or standards.

J ournaled upon the shaft D near theirlower ends are the lazy-tongs E,which are of the usual construction.

At the upper ends of the lazy-tongs E is mounteda platform, F, havingdownwardlyextending side rails, d, from which side rails extenddownwardly midway the ends thereof arms G, which are provided withvertical slots f,- or, if desired, the slot may be formed byconstructing the arms of two separate pieces. Connecting thelower endsof the arms with the top or platform are braces g. The

lower ends, and which carries a windingdrum, I.

J J represent ropes or chains secured to the winding-drum I on oppositepoints of the same, and secured at their other ends to the lower ends ofthe lazy-tongs.

It will thus be seen that when said drum is turned to wind v the ropesor chains upon it the lower ends of the lazy-tongs will be drawn towardeach other and the platform raised.

To facilitate winding and make the operation of raising the tongs easy,I have mounted on the shaft II a gear-wheel, K, meshing with which arecog-wheels L, which are located on opposite sides of the gear wheel, andare mounted upon short shafts having crank-handles g, and journaled inboxes h, secured upon the upper sides of the frame A.

F represents handles or levers by which the truck may be tilted to throwthe tongs to or from a building.

It will be understood that the platform will be lowered by the weight itsupports, and that the speed of its descent will be controlled by theattendants at the cog-wheels K.

In Fig. 3 I have shown a modification in which the upper ends of thelazy-tongs carry rollers which travel upon tracks secured to anddepending from the under side of the platform.

I am aware that fire-escapes of this class have heretofore been providedwith raising and lowering mechanism mounted on the sup porting-frame andembodying a drum, connecting-ropes, and operating-gears, and also thatplatforms have been secured at the tops of the lazy-tongs and adapted tobe carried thereby; but my invention consists in the improvedconstruction and arrangement of parts, and in the relative arrangementof the platform and engaging parts, as set forth in my claim.

Having thus described my invention, what I 5 olaimis- As an improvementin fire-escapes, the combination, with a supporting-frame carrying adrum and means for operating the same, and lazy tongs mounted upon saidframe and hav- IO ing ropes extending from their lowermost rungs to thedrum, of the platform embodying the side rails,d, from which extend thearms G, provided with vertical slots f, and the converging brace g, thetwo topmost shafts of the lazy-tong sections being extended at h, toengage, respectively, the top ends of the arms G and the slots therein,whereby the platform is braced at the upper and lower ends of theguide-arms to prevent tilting, substantially as set forth.

I11 testimony whereof I al'iix my signature in presence of twowitnesses.
